The Pi

Traditional Thai instruments used during and before the fights are the Pi, the Ching
and the Glawng Khaek.

The Pi Chawa or Java Pipe, it is believed, owes its origin to India where the
Javanese secured their model. It appears that the instrument was used in both
Royal and Army processions and in accompanying the traditional Thai fencing
bouts. The stirring sound which it makes is somewhat like the Chanta on Scotch
Bag Pipes.
